Get 4.2 Trigonometric Functions Of Acute Angles

Let h denote the length of this line AD, that is, the height (or altitude) of the triangle. When angle B is acute, then sin B = h/c.

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.

1:08 3:11 And this point here while it would have a negative x coordinate. It would have the same y coordinateMoreAnd this point here while it would have a negative x coordinate. It would have the same y coordinate. As this angle here in the first quadrant.

Acute Angle Formula It states that the sum of the squares of the two sides of a triangle is greater than the square of the largest side. In Δ ABC, if the sides measure a,b,c such that 'c' is the largest side, then, a2 + b2 > c2. In other words, in a triangle, if a2 + b2 > c2, the triangle is an acute triangle.

For any acute angle A, cofunction values of complementary angles are equal: Cofunction Identities. sin A = cos(90° - A) cos A = sin(90° - A) sec A = csc(90° - A)
